Walnut

If you are partial to walnuts but don’t have a nutcracker close by, simply place two of the nuts in the palm of your hand, squeeze, and one will magically crack open. This trick makes for a deceptively easy feat of strength and is satisfying to a degree that you may find yourself making excuses to crack nuts for others. Handily, the technique also works with other large-ish members of the nut family, such as pecans.
